2.3.3 Errors on start - Path ? [SOLVED]

Hi all
Just updated Audacity from 2.1.2 to 2.3.3.
On starting I get error boxes: one for DTMF parameters not found, then 4 about HardLimiter.

avformat-55.dll was already on the machine for Download Helper so I used Edit/Preferences in Audacity to indicate the correct path.

I dowloaded hard_limiter_1413.dll from Hard_limiter_1413.dll Download - DLL 4 Free and pasted it into
C:\Program Files (x86)\Audacity\plug-ins\hard_limiter_1413.dll

But still the errors on startup.

Below is the Debug log file.
I find strange that in the PATH string there is no semicolon (:wink: after

PATH = 'C:\Program Files (x86)\Audacity\plug-ins\

Could that be the reason for the errors or how would it be possible to solve these errors on start ?

Thanks

Pierre

I would strongly discourage downloading dll files as they can very easily be used for passing virus, trojans and/or other malware. Even if they are not malware, an incorrect version can interfere with the correct running of the computer and cause errors or instability. It is a very risky thing to do.

The “Hard Limiter” effect was discontinued in Audacity and superseded by a new Limiter effect (which can provide limiting with much less distortion): https://manual.audacityteam.org/man/limiter.html

If you actually want the distortion that the old Hard Limiter produced, you can use Audacity’s “Distortion” effect instead: https://manual.audacityteam.org/man/distortion.html and try the “Soft Clipping” preset.

The error message that you got is because when you upgraded Audacity, it retained settings for the old version. My recommendation would be:

  1. Remove the hard_limiter_1413.dll
  2. Run a full virus scan (just in case)
  3. Reset Audacity back to default settings

To reset Audacity:

  1. Quit Audacity
  2. Open the hidden folder:
    Users**\AppData\Roaming\audacity**
  3. Delete the three files:
  • audacity.cfg
    • pluginregistry.cfg
    • pluginsettings.cfg
  1. Launch Audacity.
    You should see the Welcome screen when Audacity starts.

Hi Steve
Thank you for the explanations and links.
I had no specific need of hard limiting effect. Just the error messages were disturbant.
So, even if the downloaded hard_limiter_1413.dll had been checked on extracting it from its zip file, I had no tears at scrapping it.
After having renamed the .cfg files (mine dated 31/07/2012) Audacity re-created them. Just had to add the [Recent files] to audacity.cfg.
A clean start now.
Thanks again !
Pierre

Thanks for the update.
